Hi,
I try to use Internet Explorer inside a SWT application. It's easy and it
works well for simple things.
But I can't access specific interfaces of the main component.
Is there someone having some examples or advices ?
More concretely, I create a component representing Internet Explorer as
follows :
final OleControlSite controlSite = new OleControlSite(frame,
SWT.NONE, "Shell.Explorer.2");
final OleAutomation webBrowser = new OleAutomation(controlSite);
Then, I would like to access a method SetUIHandler in an interface of this
component, with name ICustomDoc.
I've tried different ways, even the following, but none of them work.
public static final GUID IIDICustomDoc =
IIDFromString("{3050F3F0-98B5-11CF-BB82-00AA00BDCE0B}"); //$NON-NLS-1$
IDispatch objDispatch = new IDispatch(webBrowser.getAddress());
int[] ppvObject = new int[1];
//int result = objDispatch.QueryInterface(IIDIHTMLWindow2,
ppvObject);
int result = objDispatch.QueryInterface(IIDICustomDoc, ppvObject);
if (result == COM.S_OK)
System.out.print("OK OK OK - Interface found!");
else
System.out.print("NO NO NO - Interface not found!");
With C++, it could be implemented as follows:
================================
IHTMLDocument2* pDoc = ...;
ICustomDoc* pCustom = 0;
hr = pDoc->QueryInterface(IID_ICustomDoc, (void**)&pCustom);
if (SUCCEEDED(hr)) {
pCustom->SetUIHandler(pMyDocHostUIHandler);
pCustom->Release();
}
Or with C#, an implementation could be :
================================
ICustomDoc cDoc = (ICustomDoc)this.WebBrowser.Document;
cDoc.SetUIHandler((IDocHostUIHandler)this);
IDocHostUIHandler has to be implemented by your application. You can then
use ICustomDoc::SetUIHandler to tell MSHTML that you have this interface.
The interface :
==========
ICustomDoc = interface(IUnknown)
['{3050f3f0-98b5-11cf-bb82-00aa00bdce0b}']
function SetUIHandler(const pUIHandler: IDocHostUIHandler): HResult;
stdcall;
Many thanks in advance,

The SWT ActiveX support uses IDispatch interfaces to access behaviour in
custom interfaces.
Please see the following article:
http://www.eclipse.org/articles/Article-ActiveX%20Support%20 in%20SWT/ActiveX%20Support%20in%20SWT.html
and the following code examples:
